Systems, apparatus, and methods for electing a new broker for a channel on an MQTT bus

An apparatus, comprising:

• a processor coupleable to a Message Queuing Telemetry Transport (MQTT) bus;
• and
• a memory configured to store code executable by the processor to:
• maintain a set of attributes for each client device in a plurality of client devices on the MQTT bus, and
• cast a set of votes for a particular client device in the plurality of client devices on the MQTT bus to elect the particular client device as a new broker on the MQTT bus in response to a current broker on the MQTT bus becoming unavailable,
• wherein:
• the set of votes cast for the particular client device are based on a first value corresponding to the set of attributes for the particular client device relative to a respective second value corresponding to the set of attributes for each of the other client devices in the plurality of client devices on the MQTT bus, and
• the apparatus is one of the plurality of client devices on the MQTT bus.
